[GRASSLIST:281] r.out.gdal problem

[Wolfgang Zillig]

Hello,

I somehow don't completely understand the usage of r.out.gdal. I 
prepared a graphic (which is an imported tiff) with r.composite. I can 
export it with r.out.tiff without any problems. But how can I use 
r.out.gdal to export it as JPEG (or GTiff with TILED=YES). I always fail 
to specify the correct option for the required "type". I already tried 
every possibility which is listed (Byte, Int16,...), but without 
success. What "type" do I have to use?

Thanks

Wolfgang
